[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] The following is in conjunction with the appendix Figure 1-3This application provides a further detailed description. An embodiment of this application discloses a clamping fixture for the front frame of a road roller. It includes a base plate 1, with a first positioning block 2 and a second positioning block 3 on the upper surface of the base plate 1. The first positioning block 2 and the second positioning block 3 form an L-shaped positioning area. Since the L-shaped positioning area has at least two sides, at least one first positioning block 2 and one second positioning block 3 are located at the positions of the two sides of the L-shaped positioning area, respectively. To improve the positioning effect, more first positioning blocks 2 and second positioning blocks 3 can be set according to actual conditions. The front shape of the road roller front frame 8 varies, but the rear end of the road roller front frame 8 is usually square. Basic positioning is achieved by placing the rear end of the road roller front frame 8 into the L-shaped positioning area. Under the limiting and blocking effect of the first positioning block 2 and the second positioning block 3, the road roller front frame 8 will not detach from the positioning area. A first moving rod 4 is connected to the upper surface of the base plate 1, and the first moving rod 4 moves linearly back and forth towards the first positioning block 2. The first moving rod 4 moves towards the first positioning block 2, thus jointly clamping the front frame 8 of the road roller with the first positioning block 2. The angle at which the first moving rod 4 moves towards the first positioning block 2 is determined according to the specific shape of the front frame 8. A second moving rod 5 is connected to the upper surface of the base plate 1, and the second moving rod 5 moves linearly back and forth towards the second positioning block 3. The second moving rod 5 moves towards the second positioning block 3, thus jointly clamping the front frame 8 of the road roller with the second positioning block 3. The angle at which the second moving rod 5 moves towards the second positioning block 3 is determined according to the specific shape of the front frame 8. Under the combined action of the first moving rod 4 and the second moving rod 5, the front frame 8 of the road roller is simultaneously pressed tightly against the first positioning block 2 and the second positioning block 3, thus fixing the front frame 8 of the road roller in the horizontal direction.
[0017] A movable pressure block 6 is connected to the upper surface of the base plate 1. The movable pressure block 6 is located outside the positioning area and moves back and forth towards the positioning area. A fixed pressure block 7 is detachably connected to the upper surface of the base plate 1. The movable pressure block 6 and the fixed pressure block 7 fix the front frame 8 of the road roller in the vertical direction. The fixed pressure block 7 is located inside the front frame 8 of the road roller after it is placed in the base plate 1, so that the front frame 8 of the road roller placed on the base plate 1 is fixed in the vertical direction. During the process of placing the front frame 8 of the road roller into or removing the base plate 1, the obstruction to the front frame 8 of the road roller is released by disassembly. The movable pressure block 6 is located outside the positioning area to prevent the front frame 8 of the road roller from being placed into the base plate 1. After the front frame 8 of the road roller is placed into the base plate 1, the movable pressure block 6 moves into the range of the front frame 8 of the road roller and presses it down.
[0018] Furthermore, the upper surface of the base plate 1 is provided with a first connecting seat, the first connecting seat having a threaded hole, and the first moving rod 4 being a threaded rod, the first moving rod 4 being threadedly connected to the threaded hole of the first connecting seat. By rotating the first moving rod 4, the first moving rod 4 is moved linearly back and forth towards the first positioning block 2.
[0019] Furthermore, a second connecting seat is provided on the upper surface of the base plate 1. The second connecting seat has a threaded hole, and the second moving rod 5 is a threaded rod, which is threadedly connected to the threaded hole of the second connecting seat. By rotating the second moving rod 5, the second moving rod 5 can be moved linearly back and forth in the direction of the second positioning block 3.
[0020] Furthermore, to reduce potential damage to the front frame 8 of the road roller when the first moving rod 4 and the second moving rod 5 are clamping it, an elastic pad is provided at the end of the first moving rod 4 near the first positioning block 2, and an elastic pad is provided at the end of the second moving rod 5 near the second positioning block 3.
[0021] Furthermore, a connecting rod for a fixing block 7 is connected to the upper surface of the base plate 1. The extension direction of the connecting rod for the fixing block 7 is perpendicular to the upper surface of the base plate 1. The fixing block 7 has a connecting hole for the fixing block 7, and the connecting rod for the fixing block 7 is clearance-fitted with the connecting hole for the fixing block 7. A nut for the fixing block 7 is connected to the connecting rod for the fixing block 7, and the nut for the fixing block 7 is located on the side of the fixing block 7 away from the base plate 1. By rotating the nut for the fixing block 7 towards the base plate 1, the fixing block 7 moves towards the base plate 1 to achieve a pressing effect. Based on the clearance fit between the fixing block 7 and the connecting rod for the fixing block 7, the fixing block 7 can be disassembled after the nut for the fixing block 7 is removed by rotating it away from the base plate 1. When the front frame 8 of the road roller is placed into the positioning area, the connecting rod of the fixing block 7 extends into the interior of the front frame 8. Then, the connecting hole of the fixing block 7 is fitted into the connecting rod of the fixing block 7, so that the fixing block 7 is located above the internal structure of the front frame 8. The fixing block 7 is moved axially along the connecting rod of the fixing block 7 by the nut of the fixing block 7, so as to achieve the effect of pressing down and lifting the fixing block 7 relative to the base plate 1.
[0022] Furthermore, in order to improve the efficiency of installing the fixing block 7 into the fixing block 7 connecting rod, a notch is provided on the side of the fixing block 7. The notch communicates with the connecting hole of the fixing block 7 to form a U-shaped opening. The distance between the two sides of the U-shaped opening is greater than the diameter of the fixing block 7 connecting rod, so that the fixing block 7 can be inserted into the fixing block 7 connecting rod from the side through the U-shaped opening, without having to be inserted from the end of the fixing block 7 connecting rod. This significantly improves the efficiency of installing and removing the fixing block 7 and the fixing block 7 connecting rod.
[0023] Furthermore, a connecting rod for a movable pressure block 6 is connected to the upper surface of the base plate 1. The extension direction of the connecting rod for the movable pressure block 6 is perpendicular to the upper surface of the base plate 1. The movable pressure block 6 has a strip-shaped hole that extends along the direction of the movable pressure block 6 toward the positioning area. The strip-shaped hole is clearance-fitted with the connecting rod for the movable pressure block 6. A nut for the movable pressure block 6 is connected to the connecting rod for the movable pressure block 6. The nut for the movable pressure block 6 is located on the side of the movable pressure block 6 away from the base plate 1. By pushing and pulling the movable pressure block 6 along the extension direction of the strip-shaped hole, the movable pressure block 6 can reciprocate toward the positioning area. By rotating the nut for the movable pressure block 6 toward the base plate 1, the movable pressure block 6 can move toward the base plate 1 and thus press against the front frame 8 of the road roller.
[0024] Working principle: Remove the fixed pressure block 7 and pull the movable pressure block 6 to release its obstruction of the positioning area. Place the front frame 8 of the road roller into the positioning area. Operate the first moving rod 4 towards the first positioning block 2 for clamping, and operate the second moving rod 5 towards the second positioning block 3 for clamping. Push the movable pressure block 6 into the positioning area and disengage the lower part of the movable pressure block 6 from the front frame 8 of the road roller. Rotate the nut of the movable pressure block 6 to press down and tighten the front frame 8 of the road roller. Insert the fixed pressure block 7 and rotate the nut of the fixed pressure block 7 to press down and tighten the front frame 8 of the road roller.
